DevOpsPHPFor designers and developers working alone or in small teams, making websites live, or making updates can often involve remembering what has changed and manually syncing files over FTP. This fragile process can easily leave your site broken.

In this talk aimed at designers and new developers, I look at some of the ways we can improve this process.

E-commerceSecurityWe are in an age where more people have phones than toilets, and there are more active cell phones than people on the planet. How do we protect all of these devices roaming around unsecured locations, especially when they want to pay for something. Learn the secrets behind building a secure mobile backbone, as we explore how to harden security, build systems based on identity confidence, and work towards a future proofed mobile framework.

Architecture & design patternsPythonWe'll examine the "Meta" inner-class pattern used in popular python libraries such as Django, Factory Boy and Django REST Framework. The use of inner classes is part of a technique that allows for library creators to place constraints on provided customization points at class definition time. This talk will span the Python type hierarchy, how to define new types and review magic methods related to class construction.

PythonDepending on who you ask, PEP 484's Type Hints are either the next big thing in Python, or the harbinger of doom upon our entire community. Which is it? Let's find out by looking at a language that isn't Python in any way at all!

Topics covered will be proper hardware for your server, configuration settings to make the server more responsive, how to monitor your server efficiently, when to do backups, and security tips to keep data safe.

Architecture & design patternsDocumentationWhen designing a web application, drawing diagrams can help programmers understand the requirements of a project and test their mental model of implementation. UML diagrams can capture both application behaviors and data structures. Ones useful to web developers include the deployment, use case, sequence, and state diagrams. The best approach for using UML diagrams with modern web development methods like agile will also be discussed.

JavaScriptQuality assuranceWriting unit tests is a time-consuming chore; but it is necessary before we can fix bugs or develop new features. Testing AngularJS code in particular requires a lot of boilerplate. In this presentation I will show a simple helper library can remove all the extra code and allow to unit test code in seconds.

Future techAs more and more apps record audio and video we need to think about what to do with the files. Playing them back isn't enough. These files are full of data that developers can start exploiting thanks to an emergent category of signal and natural language processing technologies. Some of these are accessible via developer-friendly APIs.

HTML & CSSMobileBootstrap is one of the most popular responsive design frameworks in use today. With the release of Bootstrap 4, this powerful framework modernizes its CSS and integrates Sass as the CSS preprocessor of choice. This talk will compare Bootstrap 3 with Bootstrap 4, including identification of new features, removal of older features, and summarizing what Bootstrap 4 means for your upcoming web development work.

DatabasesDevOpsRubyDocumentationAt Red Hat we make very extensive use of Puppet to manage systems, and Hiera to make things as data-driven as possible. With thousands of systems, and hundreds-to-thousands of Hiera keys, keeping track of what affects which *could* be a monumental manual task -- but we let Hiera's own structure automatically build and maintain its own documentation with some help from Ruby scripts. In this session I show how we do it.

DevOpsLearn how to get a Vagrant environment running quickly, using a project called Oh-My-Vagrant. I'll show some tools such as vscreen & vcssh which make it possible to connect to many vm's easily. I'll demo how to integrate with config management, and how you can use these techniques to simulate clusters of containers. This talk will include live demos of building docker containers, orchestrating them with kubernetes, and all glued together nicely.
